ROPE-CLAMP.

` To 4all who-m 'it may concern America, residing at Columbus, in thecounty ofFranklin and State of--Oh1o, havey invented certain new anduseful Improve-l V tion so that it may be of the principles of SAMUELELNo Goon- Be it known that I, l

the United States of FnLLow, a citizen of ments in Rope-Clamps, of'which the following is a specification. y

The present invention relates to improvements in rope'clamps, and whileit is designed especially for use in connection with clothes lines, itwill of course be understood that the device is equally applicable forother purposes.

The primary object of the invention is the provision of a device that isfacile-in operaapplied to or detached from a rope, that 1s simple andcoinpact in construction, and is comparatively ineXpensive inproduction.

With these. objects in consists in certain novel combinations andarrangements 'of parts, essentially three in number, whereby the clampis produced as will hereinafter appear. b

In the accompanying drawings I have illustrated two= complete examplesof the physical *embodiment of my invention constructdaccording to thebest modes I have so far' devised my inventlon. In the drawings: duplexclamp made'according to my invention. ,Fig 2 is a top plan view ofFig. 1. Fig. 3 is a transverse vertical sectional view taken on eitherlines A-A in Fig. 1. Fig. 4: illustrates a single clamp, of which Fig.`5 is a top plan view and Fig. 6 a side elevation. Fig. 7 is a top planview of a modified form of the single clamp.

As before stated the device, which is the subject of the inventioncomprises essenl tiallythree elements vor members, vor at the most, fourelements are essential to complete the clamp in either one illustrated.

Referring particularly. to the duplex clamp of Figs. 1, 2 and 3, it willbe seen thatl this device includes a pair of lduplicate or complementaryclamp plates 1 and 2 formed with guide posts 1a and 2a, and open endslots 3. The plates may be of casty or stamped metal as desired, and aswilll be apparent from the drawings the posts 1a and 2a are bent atright angles to the body of their respective plates at the ends, andthese posts Specification of Letters Patent.

fit neatly intheslots 3 yat quickly and easily pose' and this ring viewthe invention aDdleO for the practical application Figure 1 illustratesa or both of the forms plates opposite to the"` Strengthening orreinforcing ribs 4: 4 eX- tend along the longitudinal outer edges of theplates, and in cross section, the body of l PatentedJ an. 4, A1916.Application led November 7, 1814.

the ends of ythe l integral posts..

the plates, 'or rather the body of each plate'4 is fashioned with anirregular surface as 5, for the purpose of providing a firmer grip 'onthe rope than would otherwise be the case.

The two vclamp nected by means l provided with right hand threads 7 andleft plates are -directly conof a screw bar which 1s hand threads 8, andthe plates are centrallyv i perforated and threaded to receive thesescrew threads, an annular flange or boss 9 being employed to furnishadditional engagement of the threaded parts. A ring or lo'oplO isconnected to the end of the screw bar, the latter beingperforated forthe purr hand grasp to be used for turning the screw bar, but performsthe additional function of a suspending ring for the rope to which the.clamp is attached, as will be described. v

In the form of the invention illustrated in the remaining figures of thedrawing a single clamp is exemplified. Here theclamp plate 11 has anangular post or tongue 12, and the plate tongue and slot co-acting as inthe other form. The screw bar 15 also performs the same function as thefirst bar and has the right hand and left hand threads 16 and 17respectively and a suspending ring 18.-v In the modied form of thesingle clamp illustrated in Fig. 7 the plate 13b is formed with a slot3b located near the end of the plate but not open as in the other forms.The .post or tongue 2b fits neatly and is ided in themodied constructionis vsuperior to the forms shown with open slots, as it labsolutelyeliminates the possibility of disenserves not only asai.

13 has the open slot 14, the

this slot, and in some instances gagement of parts while the post is inthe slot.

-The screw than the posts or tongues 1a, 2b and 2a or 12, so that byturning the screw bar the plates may be separated and the tonguesdisengaged from their slots, as in Fig. 6. When in this osition the anang e to each ot er and the clamp may be attached to al rope by locatingthe rope between a tongue'and the screw bar. The

plates are then turned to parallelism with barv is purposely made longerlplates may be turned at the tongues alining with their slots, and thebar may be turned clock-wise so that the threaded engagement causes theplates to clamp on` the rope, and in this manner the device is fixed tothe rope.

The duplex clamp isespecially adapted for clamping two ends of rope orcable or the likel together, for looping or shortening, or binding' twoparallel strands of rope together, and for many other purposes inconnection with awnings, tackle, tents, etc., where ropes are to beattached.

rllhe single clamp is wellvfitted for use, one for instance at the endsof a clothes 7 line, and when so attached, the4 line is suspended byhanging the ring 18 over a nail or hook permanently fixed in place.rlhus the line may be put up or taken down quickly and with littlelabor,knotting of the rope is eliminated, and the undesirable wrappingof the rope around sharp edges or corners or other projectionsisavoided, thus prolonging the utility and longevity of the rope. Theclamp may be slid along the rope to proper or desired position (afterirst in presence of two witnesses.

having been loosened) andjxed in adjusted position intermediate the endsof the rope, and the comparatively small size of the clamp makes it sothat the clamp will remain on the clothes line and b e wound up iaeaeaetherewith Without producing an unsightly lor inconvenient protuberance.

llt will be evident that a heavy duty clamp 'may be made involving thesesame principles to be used in hauling cables through having anendopening for said tongue forming guiding means for holding the plates inparallelism.

2. rlhe combination with a pair of co-acting clamp plates havingthreaded openings and each formed with an end slot and a tongue inengagement, of a screw bar having right and left hand threads engaged insaid threaded openings.
